The sixth stage news of the ERDF project No.

The development of a new analytical method for the analysis of 18 halogenated flame retardants including polybrominated diphenyl ethers, so-called "new" brominated flame retardants (BFR) and dehlorane-bound compounds in foodstuffs with high content of fats has been completed in the sixth phase of Project No. Gas chromatography coupled with resonant mass spectrometry of Fourier transformation ion cyclotron was used to identify and quantify pollutants. The method is suitable for testing unknown pollutants.

At this stage of the project, the development of an analytical method was performed for the determination of 164 residues and metabolites of pharmacologically active substances belonging to such therapeutic groups as antibiotics, anti-inflammatory and antiparasitic agents, corticosteroids and agents acting on the nervous and reproductive systems, hormonal and thyrostatic substances, as well as beta agonists. To assess the suitability of the developed method, 40 beef samples from different farms were analyzed. The animal test prior to slaughter showed clearly visible injection sites without registration of the treatment of the particular animals, and the analyzed samples showed positive results in the screening test for inhibitory substances.

During the sixth phase of the project the studies have been continued on molecular characterization of Listeria monocytogenes in food products using the MiSeq platform. Pulsed-field Gel Electrophoresis (PFGE) method for typing L. monocytogenes was also introduced. In the framework of the research, applying the developed methods within activity No.3., the studies have been performed on L. monocytogenes in relation to foodborne outbreaks in the European Union.

Two scientific articles have been prepared and submitted to the journals in order to ensure the transfer of knowledge gained in the project, while the three previously submitted publications are evaluated. The publication "Simultaneous screening and quantification of aminoglycoside antibiotics in honey using mixed-mode liquid chromatography-quadrupole time-of-flight mass spectroscopy with heated electrospray ionization" is published in the Journal of Separation Science, which is included in the Web of Science and Scopus databases.

The total project costs: EUR 448 530,90 (the planned ERDF aid (85%): EUR 381 251,26 and state budget aid (7, 5%): EUR 33 639,82). Implementation of the project is scheduled at the duration of thirty months (period: 01.03.2017. - 30.08. 2019).
